What is a Soft Cast?
A soft cast is made of a semi-rigid material that provides support for treating soft tissue injuries and fractures. It dries to the touch in 3-4 minutes and achieves full strength 30 minutes after application.
Patient Advice
- Keep your limb elevated when not in use, especially in the early stages, to minimise swelling.
- Exercise the joints that are not held in the cast as much as possible.
Cast Care
- Please do not allow your cast to become wet (unless specifically permitted by your doctor) as it may cause skin problems or wound breakdown.
- Please do not use any object to scratch the skin underneath your cast, as it can cause an ulcer to develop.
- Do not cut, heat or remove your cast unless advised to do so by your Doctor/Nurse.
Removing a Soft Cast
Soft Casts are removed by unwinding or unravelling the cast as demonstrated by the plaster nurse.
